1'0 all whom it may concern:

Be it known that I, Mvnns A. GARRETT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tank-Cars, of which the following is a specification.

l'leretofore the common practice has been to construct tank cars by forming a sup-- porting frame having center sills, and mounting the tank proper, which generally has been of a cylindrical shape, upon the frame and above the center sills. For tanks of limited capacity such construction was, for the most part, unobjectionable. \Vith the increase in the size of the tank the center of gravity was raisedso far that on curves the car tipped over and many wrecks resulted. Further, in bufiing the frame has often been shifted relative to the tank, or the latter shifted relative to the former, due to the inertia of the tank and its contents, or to the momentum of the same relative to the frame;

The object of my invention is to obviate the objections appertaining to tank cars constructed as described, and as otherwise constructed, and to provide a tank car of relatively large capacity, relatively low center of gravity when loaded, and with a tank made separate from the frame and removably anchored thereto in such a way that the tank and frame shall preserve their fixed relative positions each to the other under My invention consists in constructing a frame .with strong and rigid ends for the entire width of the frame at and in front of the body bolsters, uniting the outer ends of the body bolsters by strong girders so as to leave a relatively large unobstructed open space at the center, and supporting -upon said,fraine a tank, the center lower partorwall of which occupies a position below the lower horizontal plane of the body bolsters, and relatively near the road bed.

lt further consists in certain novelties of construction and combinations of parts as hereinafter set forth and claimed.

The accompanying drawings illustrate one complete example of the embodiment of the invention and three modifications constructed according to the best specific modes of procedure I have so far devised for the purpose.

Figure 1 is a side view in elevation of the frame and tank. Fig. 2 is a side elevation of the tank removed from the frame. Fig. 3 is a cross section near the center of the tank on line B-B. Fig. 4 is a cross section of thetank on line AA, Fig. 5 is a top plan view of the frame; the straps and end casting being removed "from the left hand half thereof. Fig. 6 is a half sectional and half side elevation view of the frame. Fig. 7 is a cross section of Fig. 5 on line (l-( Fig. 8 is a cross section of Fig. 5 on line l).--D. Fig. 9 shows the end casting riveted directly to the flan es of the beams which constitute the end rame; the cover plate being omitted. Fig. 10 shows the castingwith the horizontal inner web Omitted. Fig. 11 shows a modification of the tank.

Referring to Figs. 1 to 8, the numeral 1 designates side steel channel beams extending the entire-length of the frame and with their fiangesextend'ing outwardly; 2, the channel end sills, in this instance with the flanges, extending inwardly, but they may extend outwardly; 3., webbed connection angles riveted to the webs of the beams 1 and the end sills at their junctions; 4, two parallel channel beams at each end spaced apart-and'joining the beams 1,1 and located at a suitable distance from the end sills and constituting body bolsters; 5, connection angles riveted to the webs ofbeams- 1, 1 and beams 4 at their points 'of junction; 6, two parallel channel beams at each end located between an end sill and body bolster and constituting draft and buffer beams; 7, connection angles uniting the beams 6 at their ends to the end sills and body bolsters; 8, spacing or filling plates or blocks located between the two channel beams forming a body bolster and secured to said beams by connection angles, as shown; 9, two channel beams, in this instance of greater depth than the beams 1, located a suitable distance inwardly from and parallel with beams .1 and connected at, their ends with the body bolsters through the medium of connection angles, the lower flanges of the ends of said beams being bent upwardly at 10, so as to rest upon the flanges of the channel beams forming parts of the body bolsters; 11 and 12, top and bottom metallic cover plates riveted to the .fianges of beams l and 9 throu hout their entire lengths between the body holsters, thus forming two very rigid box girders at the sides of the frame extendabove the body bolster, side sills and end- Y sill; and are two steel castings, one at thermore, the box each end of the frame, each casting having a horizontal web 16, a raised flange 17 ohliquely disposed to the 'web and extending around three sides of the same,: and vertical strengthening ribs or webs 18 outside the flange and uniting the web and flange; said casting being secured in position by rivets passed through the web of the casting, the cover plate 14, the flanges of beams 1, the end sill, the draft beams and both the channels constituting the body bolster.

As shown and described, the combination of parts formsa very rigid structure with arelatively large and unobstructed open space between the body bolsters and the side box girders, which structure. is adapted to withstand strains from alldirections. In buffing the strains are at first taken by the draft sills, body bolsters and castings and trans mitted to the side box girders which abut the body bolsters, cover lates and horizontal webs of the castings an are in line with the side flanges of the castings. Center sills may thus be omitted from the frame. F urirders are stiff enough to support the loaf between body bolsters without truss rods, though truss rods may be used if desired, and they are also stid enough to prevent spreading or displacement sidewise. i

In Fig. 9 the casting 15 is shown riveted direct to the flanges of the side sills, end sill and body bolster, the cover plate 14 being omitted,

In Fig. 10 the cover plate is present, but the horizontal inner web 16 omitted, the flange occupying the same position as in other forms.

The tank is of the general shape shown. The upper part above a horizontal plane coinciding with the top surface of the frame is of an arched or semi-cylindrical shape and closed at the ends, said tank being made of metalplates bent and riveted together in a well known way. The lower metallic plate or plates 19 of the tank atthe ends are flat so that they lie in direct frictional contact with the entire top surfaces of the webs of the castings inside the flanges (or the cover plate 14 when the web 16 is omitted) and the froiit'endsof the tank abut the end flanges of the castings which are in line with, or parallel with, and above the end sills, so thatth'e flanges of the end castings prevent endwise displacement of the tank. The side flanges of the castings also prevent sidewise displacement of the tank.

Back of each body bolster the bottom of the tank is fashioned to form substantially vertical walls 20. 20, which abut. or lie ad-. jacent to.the vertical surfaces of the bolsters, and for a distance toward the center from these vertical walls the bottom of the tank is on the inside concave. as at 21. 21, to clear the truck wheels and frame. The vertical walls 20 and curved or concave bottom portions 21, 21. form heels. which, additional to the end flanges of the castings. prevent endwise movements of the tank.

The intermediate lower portions of the metal plates constituting the bottom of the tank between the trucks are bent. or fashioned, to form a horizontal or slightly concave wall 22, vertical walls 23, 23. and narrow horizontal surfaces 2-1, 24: at each side of the tank constituting flanges which frietionally engage and rest upon the inside top edge surfaces of the box girders, as shown. Obviously, the central portion of the tank is supported immediately by the straps 13 and mediately by the box girders, which latter in turn are supported at their ends by the body bolsters. The tank may be provided with a filling dome and a discharge spout having a valve of a well known con struction or otherwise. The tank is anchored to the frame by a suitable number of straps EBB-threaded at their ends, threaded bolts 26 passed up through the box girdels, and turnbuckles 27, as will be clearly understood from an inspection of the drawings; but other means for the purpose may be employed. As shown in Fig. 11, the horizontal seats 24, 24 at the sides of the tank may be omitted and the entire weight taken directly by the straps.

The car comprising the frame and tank connected therewith, as shown and described, has a relatively low center of gravity when the tank is filled with oil or other 1 liquid and thus it will not tip over on curves. The tank can easily be removed from the frame when repairs of either the tank or frame are necessary. The frame itself is so constructed that it will effectively resist strains imparted from any direction, and especially those incident to drawing and buffing, by reason of the presence of the end castings with their wide webs and the box girders,and the tank itself is securely anchored against endwise movements, or displacement, relative to the frame by reason of the presence of the flanges at the ends of the castings and the heels formed in connection with the tank, which heels abut, or lie, ad jacent the body bolsters.
